Description

Technical Field

[0001] The invention relates to the technical field of waste gas treatment devices, in particular to an atomizing mixer for waste gas condensation treatment. Background Art

[0002] Waste gas refers to harmful gases discharged by humans during production and life. There are many types of pollutants in waste gas, and their physical and chemical properties are very complex and their toxicity varies. Industrial waste gas generally contains solid particulate matter, sulfides and nitrates, which are the main source of air pollution. The respiratory waste gas produced by the human body generally contains aerosols. The bacteria and viruses suspended in the aerosols can easily spread diseases. For example, the new coronavirus-induced COVID-19 can be spread through aerosols. Therefore, the discharge of waste gas into the air will seriously pollute the environment and affect human health. Existing waste gas treatment devices generally have complex structures and high equipment costs. A single device cannot simultaneously and efficiently remove multiple pollutants such as solid particulate matter, sulfides, nitrates and aerosols. Summary of the invention

[0003] The purpose of the present invention is to provide an atomizing mixer for waste gas condensation treatment, which overcomes the shortcomings of the above-mentioned prior art, has a simple equipment structure and low cost, and can simultaneously and efficiently remove pollutants such as solid particles, sulfides, nitrates and aerosols through a single device.

[0004] The technical solution adopted by the present invention to solve the technical problem is:

[0005] An atomizing mixer for waste gas condensation treatment comprises a box body, a nozzle seat is arranged in the box body, the main body of the nozzle seat is a cylindrical structure, one end of the nozzle seat is connected to the front end of the box body, and the other end of the nozzle seat is connected to the rear end of the box body. A plurality of rows of nozzles are evenly distributed along the circumferential direction on the side wall of the nozzle seat, and two adjacent rows of nozzles are separated by a partition plate, and through holes are evenly distributed on the partition plate, and the nozzle seat is connected to a liquid inlet pipe; a liquid outlet pipe, an air inlet channel and an air outlet channel are arranged on the side wall of the box body, a mixer seat is installed on the air outlet channel, and a mixer is installed on the mixer seat; when in use, the waste gas treatment liquid enters the liquid inlet pipe, and the waste gas treatment liquid is sprayed into mist through the nozzle on the nozzle seat. The waste gas to be treated enters the box through the air inlet channel, and the waste gas is decelerated, depressurized, and accumulated through the partitions in the box, and is fully mixed with the mist-like fine droplets sprayed from the nozzle to form a liquid-gas mixture. The liquid-gas mixture enters the mixer through the air outlet channel of the box. In the mixer, the mist droplets in the liquid-gas mixture further absorb the harmful components in the gas, and the gas after the harmful components are absorbed is discharged from the box. The solid particles, sulfur-containing compounds, nitrate-containing compounds, aerosols and other components in the waste gas have been fully absorbed and dissolved by the atomized small droplets and are discharged from the liquid outlet pipe together with the small droplets.

[0006] Furthermore, the mixer seat is installed at the end of the air outlet channel by fasteners, the mixer seat is evenly distributed with mixer mounting holes, and the mixer is installed in the mixer mounting holes. The installation method of the mixer seat and the installation method of the mixer are conducive to convenient disassembly and installation of the mixer seat and the mixer.

[0007] Furthermore, the mixer includes a drainage chamber, a mixing chamber and a diffusion chamber in sequence. The inner diameter of the drainage chamber gradually decreases from the starting end to the end. The mixing chamber is a cylindrical cavity structure. The inner diameter of the diffusion chamber gradually increases from the starting end to the end. The liquid-gas mixture flows to the drainage chamber driven by the gas, and the fine droplets in the drainage chamber are pressurized to further absorb harmful components in the exhaust gas. When reaching the mixing chamber, the pressure increases to the maximum, and the droplets that absorb and dissolve the pollutants in the exhaust gas reflux under the action of gravity, and the gas that has been free of pollutants is discharged to the diffusion chamber through the mixing chamber, and is discharged into the air after the diffusion chamber is depressurized.

[0008] Furthermore, the drainage chamber of the mixer includes a first through hole, a second through hole and a third through hole, the first through hole and the third through hole are both truncated cone-shaped cavity structures, the second through hole is a cylindrical cavity structure, the starting diameter of the first through hole is larger than the ending diameter, the diameter of the second through hole is equal to the ending diameter of the first through hole and equal to the starting diameter of the third through hole, and the ending diameter of the third through hole is smaller than the starting diameter; the diffusion chamber of the mixer includes a fourth through hole, a fifth through hole and a sixth through hole, the fourth through hole and the sixth through hole are both inverted truncated cone-shaped cavity structures, the fifth through hole is a cylindrical cavity structure, the starting diameter of the fourth through hole is smaller than the ending diameter, the diameter of the fifth through hole is equal to the ending diameter of the fourth through hole and equal to the starting diameter of the sixth through hole, and the ending diameter of the sixth through hole is larger than the starting diameter; the gas-liquid mixture flows to the first through hole of the drainage chamber driven by the gas, and is gradually pressurized in the first through hole Then it enters the second through hole for voltage stabilization. The main functions of the voltage stabilization stage are: first, to promote the droplets to fully absorb the pollutants in the solution exhaust gas during the voltage stabilization stage; second, to prevent the gas-liquid mixture from being continuously pressurized and the liquid from being brought into the diffusion chamber. After the voltage stabilization is completed, the liquid-gas mixture continues to enter the third through hole, and is pressurized twice in the third through hole. 99.9% of the solid particles, sulfur-containing compounds, nitrate-containing compounds, aerosols and other pollutants in the exhaust gas are absorbed and dissolved by the droplets. When the liquid-gas mixture reaches the mixing chamber, the pressure reaches the maximum, and the droplets flow back under the action of gravity and are discharged from the liquid outlet pipe. The purified gas enters the diffusion chamber from the mixing chamber and is quickly depressurized in the fourth through hole of the diffusion chamber. The depressurized gas enters the fifth through hole. During the mixing process, a very small amount of liquid will be brought to the diffusion chamber by the gas, and the liquid will quickly release pressure and flow back in the fourth and fifth through holes of the diffusion chamber, and the gas will be diverted to the sixth through hole through the fifth through hole and finally discharged.

[0009] Furthermore, an auxiliary drainage chamber is provided on the side wall of the mixer, and the inner diameter of the auxiliary drainage chamber gradually decreases from the starting end to the end end, and the end of the auxiliary drainage chamber is connected to the fourth through hole of the diffusion chamber. The main function of the auxiliary drainage chamber is to accelerate the processing efficiency of the gas in the mixer. Part of the liquid-gas mixture in the box body enters from the auxiliary drainage chamber and is gradually pressurized in the auxiliary drainage chamber. The liquid fully absorbs the harmful substances dissolved in the exhaust gas, and part of the liquid flows back into the box body during the pressurization process. A small amount of liquid enters the fourth through hole of the diffusion chamber with the gas, mixes with the gas discharged from the mixing chamber to release the pressure, and fully absorbs the harmful substances remaining in the mixed gas from the mixing chamber. Then, the liquid in the depressurized state flows back into the box body, and the gas is guided to the sixth through hole through the fifth through hole and finally discharged.

[0010] Furthermore, the end surface of the box body can be disassembled.

[0011] Furthermore, the box body includes a box body main body, a blind end flange and an end flange, the box body main body is a cylindrical structure, both ends of the cylindrical structure are provided with inner edges, a blind end flange is installed on the inner edge of one end of the cylindrical structure through fasteners, and an end flange is installed on the inner edge of the other end through fasteners, and a nozzle seat through-hole is provided in the middle of the end flange; this structural setting mode of the box body is conducive to installation and disassembly, and the box body can be disassembled in time for repair and replacement when the internal structure of the box body is damaged.

[0012] Furthermore, the open end of the main body of the nozzle seat is provided with an outer edge, the nozzle seat main body is inserted into the box along the nozzle seat perforation, the sealing end of the nozzle seat is in conflict with the blind end flange of the box, the outer edge is stuck outside the nozzle seat perforation, and the outer edge is installed on the end flange by fasteners. This setting method of the nozzle seat is conducive to disassembly, maintenance and replacement.

[0013] Furthermore, the main body of the nozzle holder is a cylindrical structure with one end open and the other end sealed, which facilitates the installation of the nozzle holder.

[0014] Furthermore, an air supply pipe is provided in the box body, one end of which is connected to an external air supply device, and the other end of which extends into the beginning of the drainage chamber to provide compressed air for the drainage chamber, thereby enhancing the mixing efficiency of the droplets and pollutants in the exhaust gas.

[0015] The beneficial effects of the present invention are as follows: compared with the prior art, the atomizing mixer for waste gas condensation treatment of the present invention has the following advantages: the equipment has a simple structure and low cost, and can simultaneously and efficiently remove solid particulate matter, sulfide, nitrate and aerosol and other pollutants through a single device, and the removal rate of target pollutants reaches 99.9%; when in use, the waste gas treatment liquid enters the liquid inlet pipe, and the waste gas treatment liquid is sprayed into mist-like fine droplets through the nozzle on the nozzle seat, and the fine droplets are distributed in each chamber separated by the partition, and the waste gas to be treated passes through the inlet pipe. The exhaust gas enters the box through the channel, and the exhaust gas is decelerated, depressurized, and accumulated through the baffles in the box, and is fully mixed with the mist-like fine droplets sprayed from the nozzle to form a liquid-gas mixture. The liquid-gas mixture enters the mixer through the gas outlet channel of the box, and the mist droplets in the liquid-gas mixture in the mixer further absorb the harmful components in the gas. The gas after the harmful components are absorbed is discharged from the box. The solid particles, sulfur-containing compounds, nitrate-containing compounds, aerosols and other components in the exhaust gas have been fully absorbed and dissolved by the atomized small droplets and are discharged from the liquid outlet pipe together with the small droplets.
